Display

Our review unit showed a peak brightness of around 368 cd/sq.m., which is an OK result for a budget smartphone. Moreover, it even showed relatively good black values, resulting in a very high contrast ratio of around 2500:1. The latter is Oukitel K7000 Review really consistent at all brightness levels the only exception being when the brightness is set at 0%. At this level the white and black values are 46.572 cd/sq.m. and 0.030 cd/sq.m., respectively, hence, the contrast ratio is 1552:1. Another feature of the display that can be a Oukitel K7000 Review deal breaker is its temperature of the white point. It is not disappointingly high and is actually consistent at all brightness levels, measuring an average of 9000 K. This means that the colors look colder. The software settings do not offer any options for correcting color temperature, saturation, contrast or any other feature for that matter.

Primary camera

The choice of sensor for the primary camera hints at the fact that this is not deemed to be a main selling point. The main shooter of Oukitel K7000 is equipped with a 5-megapixel GalaxyCore GC5005 sensor. This type of sensor can be found only Oukitel K7000 Review in the most budget devices. It has a 1/5″ size and its pixels are 1.12μm large. It should make images with a resolution of 2608 x 1960 pixels, but being interpolated to 8 megapixels, it makes images with a resolution of 3264 x 2448 pixels. Interpolation does no good to any Oukitel K7000 Review kind of images. According to the specifications, the camera should make 720p videos at 30 fps, however, the videos are with a resolution of 640 x 480 pixels at 30 fps.

Secondary camera

The front-facing camera sports a 2-megapixel GalaxyCore GC2365 sensor with a 1/5″ size and 1.65μm pixels. It should make images with a resolution Oukitel K7000 Review of 1600 x 1200 pixels, but is interpolated to 5 megapixels, so the images are with a resolution of 2560 x 1920 pixels.

Battery

Oukitel K7000 packs a 2000 mAh Li-Pol battery with a standard 5V/1A charger. The software of the device includes a Power Saver app, which includes two power saving modes – Super power saving mode and Smart-saving mode, which is switched on by Oukitel K7000 Review default. In addition, the battery monitor includes a Standby intelligent power saving mode, which is switched on by default as well. The software provides Battery optimization and Battery saver options as well. You can also select specific apps, which should be protected from all power saving modes. The most noteworthy feature of the model is its power bank, which Oukitel K7000 Review arrives with a 5000 mAh battery integrated in it, a USB 2.0 port, and a bracket, which allows you to use it as a stand for the smartphone. You can also use it as a protective case. It has four blue dots serving as a light indicator for its own charge. Each dot corresponds to 25% of Oukitel K7000 Review the charge. The power bank has a dedicated button, which should be pressed in order charging to start. If pressed and hold for 3 seconds it turns off.

We have made two measurements for the battery charging and the battery temperature while charging. The first graph demonstrates those two parameters when the device is charged with its standard 5V/1A charger. It took a total of 4 hours to charge the 2000 mAh battery of the device from 0% to 100%. The charging rate has been steady throughout Oukitel K7000 Review the whole process. After the first hour the battery reached 30%. After another hour it reached 53%. At the third hour of charging, the capacity reached 78%. The battery temperature did not fluctuate a lot. It started at 36°C, dropped to 32°C, and went up to 37°C when the battery reached 25% of its capacity. This level remained unchanged till 68% of the battery’s Oukitel K7000 Review capacity and started dropping down to 30°C, when the battery reached 100%. We also did another test to check how long would it take for the 5000 mAh power bank itself to be charged. It took 5 hours and 40 minutes to reach 100% from 0%.The second graph depicts the battery charging and the battery temperature while charging from the power bank without a cable. It is obvious that the battery charged much faster – for 3 hours and 10 minutes. The charging rate was steady and dropped only after the battery reached 90%. Charging stopped automatically, when the battery reached 98%. We tested this several times. When the battery is charged from 0% to 98%, the light indicator on the Matrix shows that it still has left 25% of its own charge.As long as it concerns the PCMark Work battery test it could be performed only without the power bank. We did try to test the device with the Matrix, but the software decided that the phone is plugged into a charger and could not run Oukitel K7000 Review the test. The test has been performed with the display brightness calibrated at 200 nits as recommended by Futuremark. The result of the test is 4 hours and 35 minutes, which is a very good result for a 2000 mAh battery.

Audio

The Music app is standard for Android 6.0 Marshmallow. It can sort the on-board audio files according to the artists, albums, and songs. There’s a Oukitel K7000 Review tab for playlists as well. The app has an integrated equalizer offering various effects. HotKnot sharing is also integrated in the Music app.

Oukitel K7000 has a standard audio equipment and provides average audio quality. It scores Excellent in frequency response and Oukitel K7000 Review Good in THD + Noise, with all other parameters being evaluated as Very good, which forms the same overall score. The speaker is typical for a budget smartphone and the sound coming out of it is often tinny.
